SPECIFICATION forming part of Letters Patent No. 713,825, dated November18, 1902.

Application iiled May 6,1902. Serial No. 106,194. (No model 1o improvethe construction of anchors and to provide a stockless anchor of simpleand inexpensive construction which will be positive and reliable inoperation and which will automatically reverse itself when a ship x5swings to the opposite tide.

A further object of the invention is to provide an anchor which when letgo will firmly engage the bottom and which will be maintained in suchengagement by the strain to zo which it is subjected, so that thegreater the strain the greater will be the holding power of the anchor.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective view of an anchor constructedin accordance Fig. 2 is a transverse sectional View. Fig. 3 is alongitudinal sectional view.

Like numerals of reference designate corresponding parts in all thefigures of the drawings.

l designates the head or body of an anchor provided with a centralapproximately cylindrical bearing portion 2 for the reception of one endof a shank 3, which is provided with 4olaterally-projecting trunnions4f, forming a inward from the bottom and provided with curved innerfaces 6, located at opposite sides of a narrow curved slot 7, throughwhich the shank extends and in which the shank is adapted to oscillate,for a purpose hereinafter The shank is introduced into'thebearing-recess from the bottom of the head,

and the trnnnions extend laterally beyond the slot 7, and the shank isthereby pivotally connected with the head or body and is adapted tooscillate freely.

The head or body of the anchor is also provided with side portions 8,which may be formed integral with the central bearing por tion; butinstead of forming the head or body of a single casting the sideportionsand the central bearing portion may consist of separate casingsand be suitably secured together. Each side portion is provided with apair of diverging flukes 9, consisting of approximately iiat'blades,rounded or tapered at their outer ends. One of the nukes of each pair isadapted to embed itself in the bottom and the other fluke is designed tolie upon the surface ofthe bottom,whereby any strain on the shanktending to drag the anchor will force the lower fluke downward into thebottom and will crowd the material of the bottom between the flukes,whereby the holding power of the anchor will be increased with thestrain to which it is subjected. The side portions are also providedwith oppositely-disposed supplemental fiukes l0, located atdiametrically opposite points and tapered toward their outer ends toenable them to readily embed themselves in the bottom. Thesesupplemental lukes or extensions, which are located at the base of thetiukes i), are adapted to produce a positive reversal of the anchor, andthey also cause the flukes to positively engage the bottom when theanchor is let go. Vhen the anchor is let go, it drops to the bottom, andthe lower supplemental fiukes will be embedded in the bottom, and whenthe ship drags upon the shank the body or head will partially rotate onthe supplemental flukes to direct the lower main flukes into the bottom,and the said lower main lukes will be forced into the bottom by thestrain on the anchor. When the ship swings to the opposite tide, theshank will be oscillated and will partially rotate the head or body andcarry the other set of supplemental flukes downward. These supplementalflukes will thenv be embedded in the bottom, and the strain on theanchor will complete the rotary movement of the head or body and engagethe lower main flukes with the bottom. The anchor is adapted to auto-ICO matically reverse itself in this manner and the trouble andinconvenience of resetting are obviated.

The shank and the head or body of the anchor are readily assembled, andas the parts are of great strength and durability. there is no liabilityof a -break at the point of connection. The anchor when drawn up to thehawser-pipe of a ship will set as close as an ordinary single-flukeanchor, and should one of the iukes become broken the anchor Will be aseective as a single-duke anchor.

The shank is confined in the bearing-recess 5 by means of. a pin or key1l, extending across the recess 5 at a point beyond the trunnions llandhaving its ends fitted in snitable sockets 12, which are formed in theopposite walls of the recesses. The pin is applied to the head or bodyafter the other parts have been assembled, and before being applied itis bent and heated, the bending being su fcient to enable it to beintroduced into the recess with its terminals opposite the sockets. Thepin or key is then straightened to carry its ends into the sockets 12,and after it becomes cool it will be firmly secured to the head or body.This will effectually prevent the shank from slipping ont of the head orbody, and it will also prevent the shank from becoming lost should thechain break and it become necessary to drag for the anchor.

It will be seen that the anchor is simple and comparatively inexpensivein construction, that it possesses great strength and durability, andthat the parts are readily assembled. It Will also be apparent that theanchor is effectually prevented from dragging and that it is capable ofautomatically reversing itself When the tide changes and the vesselswings to the opposite tide.

What I claim is- 1. An anchor comprising a shank and a head or bodypivotally connected With the shank and capable of a limited rotarymovement, said head or body being provided at each side with a pair ofdiverging flukes arranged to be carried to either side of the shank bythe said rotary movement, whereby one iiuke of each pair Will embeditself in the bottom and the other fluke Will lie upon the surface ofthe bottom, substantially as described.

2. An anchor consisting of a head and a shank, the head being providedat each side With a pair of diverging pivotally-mounted flukes arrangedto swing to either side of the shank, one fluke of each pair beingadapted to embed itself in the bottom and the other fluke being arrangedto lie upon the surface of the bottom, substantially as described.

3. An anchor comprising a head or body provided at opposite sides withdiverging flukes and having oppositely-disposed supplemental finkeslocated at the base of the said lukes and adapted to produce a positivereversal of the anchor, and a shank pivotally connected with the head orbody, substantially as described.

4. An anchor comprising a shank, and a head or body provided at oppositesides of t-he shank with diverging linkes arranged in pairs, said heador body being also provided at the base of the said linkes withoppositelydisposed supplemental liukes, substantially as described.

5. An anchor comprising a body composed of a central approximatelycylindrical bearin g portion having a bearing-recess and provided with aslot, and side portions each provided With a pair of diverging mainflnkes and having oppositely-disposed supplemental inkes extendingoutward from the base of the main linkes, and a shank arranged in thesaid slot and provided with trunnions located in the bearing-recess,substantially as described.

In testimony that I claim the foregoing as my ovvn I have hereto affixedmy signature in the presence of two Witnesses.
